I am assuming you are on some sort of VPS (Virtuozzo most likely -- just a guess) and seeing errors such as this:

Code:

error: unpacking of archive failed on file /usr/lib64/mysql/plugin/ha_example.a;4bdbf297: cpio: open failed - Not a directory

most likely means that your VPS cache is corrupted or missing files. If you do a

Code:

ls -la /usr/lib64/mysql/plugin/

You will most likely see files with ??????? for attributes or they will be flashing in red. This is something your VPS provider needs to repair as your VPS cannot overwrite the files because there is issues with your VPS cache.
